CALK ATTACHMENT FOR HORSESHOES.

SPECIFICATION forming part of Letters Patent No. 623,896, dated April 2 5, 1899. Application filed September 12, 1898. b'erialNo169Ofi54. (No model.)

To ail whom, it ntay concern.-

Be it known that I, KARL J ULIUs GAITZSCH, a subject of the King of Saxony, residing at Knauthain, Kingdom of Saxony, Germany, have invented a certain new and useful Calk Attachment for Horseshoes, of which the following is a full, clear, and exact description.

The present invention relates to a calk attachment for horseshoes; and it consists of the details of construction hereinafter set forth, and particularly pointed out in the claims, and in order to render the present specification more easily intelligible reference is had to the accompanying drawings, in which similar letters of reference denote similar parts throughout the several views.

Figure 1 is a view, seen from underneath, of parts of a shoe provided with screw-calks; Fig. 2, a section on line a a of Fig. 1. Fig. 3 shows the end of a shoe with a screw-call: seen from underneath. Fig. 4: is a section on line b b of Fig. 3; Fig. 5, a similar section with the tongue bent inwardly; Fig. 6, a section on line 0 c of Fig. 3. Fig. 7 is a View, seen from underneath, of a part of a shoe having a calk adapted to be slid into the groove of the shoe. Fig. 8 is a section on line at d of Fig. 7. Fig. 9 shows the shank of the shoe with asimilarly-attached calk to that of Fig. 7 seen from underneath. Fig. 10 is a section on line 9 g of Fig. 9; Fig. 11, a similar section with the tongue turned in; Fig. 12, asection on line 72. h of Fig. 9. Figs. 13, 14:, and 15 are sectional representations of various forms of calks. Fig. 16 is the shank end of a shoe, showing a calk adapted to be slid into position and provided with a covered locking-tongue; Fig. 17, a view, seen from underneath, of a calk having a covered swallow-tail tongue. Fig. 18 is a view, seen from underneath, of a shoe with a disengaging groove and a swallow-tail retaining-recess. Figs. 19 and 20 are representations of a part of a shoe and a screw-call; having a covered tongue.

In the drawings, in all the figures z designates a laterally-exten ding tongue on the calk. a is a recess in the shoe,into which said tongue may be turned or bent. at is an extension of the said groove or an auxiliary groove, by

means of which a tool or instrumentmay be inserted underneath the tongue when it is re quired to bend the same back out of its groove in taking out or exchanging the calks.

a is a lateral extension of the grooves, which also serves to facilitate the bending back of the lateral tongue z in removing the calk.

In Figs. 1 to 7 the call; is first inserted in the ordinary manner,and the laterally-extending tongue .2 is then bent or deflected into the groove or recess a, so that the calk is properly fixed and cannot under any circumstances get loosened. In Fig. 9 the call: is slid into a guideway on the shoe and then secured by means of the tongue .2, which is bent around, as specified. In this case the side grooves or recesses form extensions of the recess, into which the tongue is bent, this recess being simply broadened at either side. The groove or recess, which serves to facilitate the extraction of the tongue, may be arranged at any part of the retaining-groove as may appear desirable. In the case of the front calk, as shown at Figs. 1 and 2, a tongue may be provided at both ends, as also corresponding recesses. As shown at Fig. 17 the tongue may be laterally tapered at the end next the calk and may be protected against damage or wear by means of a protecting-covering. (See Figs. 16 and 20.)

The device secures the calk absolutely, each tread of the horse tending to press the tongue farther into its recess.

I claim as my invention 1. The combination of a horseshoe having a recess 72, lateral extensions (1 to said recess, and a longitutional extension at to the same, a calk having laterally-extending tongue 2 adapted to be deflected into said recess 01 and extending across said lateral extensions a in the manner and for the purpose substantially as described.

2. The combination of a horseshoe having a recess in proximity to the calk, and a calk having a laterally-extending tongue adapted to be deflected into said recess and a protecting-covering to said tongue in the mannerand for the purpose substantially as described.

The combination of a horseshoe having a depression in proximity to the ealks, later- In witness whereof I have hereunto set my ally-extending recesses in communication hand in presence of two Witnesses.
